I have been diagnosed with pernicious anaemia without anti-IF antibodies. It has likely been very low for very many years and was only treated from summer last year with loading shots then 8 weekly shots after that. I had supplemented myself prior to diagnosis but that had had no effect.
For some reason I suddenly developed bad parasthesia in my hands and my feet in January (or had it started before and I just hadn't noticed?). It was constant, not coming and going like when you have a dead leg.
Anyway I had my latest B12 shot yesterday and it seems a lot better already today. That doesn't seem right does it? Surely it's too quick? Everything else B12 related took weeks or months to resolve.
My first question is: is the time since the shot (24hrs) too little for the improvement to be related to the shot?
My second question that is I get very, very swollen veins the evening after a shot. Is that anything to worry about? They are absolutely massive, all sticking out like a very old person. It's horrible to look at tbh, but obviously I'm just worried about having a blood clot or a stroke etc.
Thanks for any thoughts.
